W A T L O WTemperatureControllersFor <strong>com</strong>plete information onMLS300 controllers referencepages 253 to 256.16-, 32-LoopMLS300The Watlow MLS300 is a powerfulline of controllers that <strong>com</strong>bineperformance and flexibility with<strong>com</strong>pact design. The 16 and32-loop versions provide <strong>com</strong>pletecontrol solutions for plasticsapplications. Support for multipletypes of sensor inputs is available;including thermocouples, RTDs,linear voltage, current and frequency.Each controller can operate as astand-alone system, and includesbuilt-in serial <strong>com</strong>munications for<strong>com</strong>puter interface and data acquisition.The enhanced features optionoffers cascade, ratio and differentialcontrol, process variable retransmitand remote analog set point.The remote analog input optionsallow for shorter sensor wires andflexible mounting which reducessensor cost and installation time.Watlow’s new CIM option providesOEMs with a space and labor savingalternative to the standard AIMmodule. This innovation allows usersto construct a wiring harness toattach sensors via a connectorinstead of connecting individualwires to the controller.The MLS300 controllers are UL ® andC-UL ® listed, meet the requirementsof the European Community EMCDirective and carry the CE mark.Features and BenefitsPID control of up to 16 heat andcool loops or 32 heat loops• Minimal panel space per loop• Reduces installation time• More reliable: fewer parts meanfewer failuresAuto-tuning• Less time tuning• Achieve excellent control with lessexpertiseMenu guided operation with fulltext display• Quick controller setup• Easy to operateEight jobs stored and recalled• Quickly change from one processto anotherMultiple and mixed inputs• Simply change sensor types atthe last minute• Less to learn, less inventorySensor fail detection• Reduces time troubleshootingreversed, shorted and opensensorsHigh/low process and deviationalarms for each input• Configure alarms as needed tointegrate with PLC or other controlelementsTIA/EIA-232 and 485<strong>com</strong>munications• Use software to configure andoperate• Integrate with other controllersand software34 digital outputs• Flexible configuration: use outputsas needed for control, alarms andprocess variable retransmitCIM300 option• Small footprint per loop• Reduced installation timeWatlow’s WATVIEWsoftware is ideal touse with the MLS300.See page 180 for moreinformation andordering details.ThermoformingTemperature Controllers331
